A bomb blast rocked the main market of the city of Maiduguri in north-eastern Nigeria Tuesday, with multiple deaths feared, witnesses said.
The website Sahara Reporters put the number of victims at 25.
Witness Abu Modu said a suicide bomber blew himself up at the entrance to the market.
"As people were about to go for their midday prayers, the man hurriedly entered the market and there was a loud explosion. People scattered to safety, but many were killed," he said.
Sahara Reporters said the bomber was female.
